Abstract: A quick release attachment mechanism to releasably join a stand mixer drivetrain to an attachment insert. The mechanism includes one or more retaining balls to axially fix the attachment insert in the assembly and a plurality of cooperating walls to fix the attachment insert against rotational displacement.

Abstract: A stand mixer is provided having a motor, an attachment support coupled to the motor, a mixing shaft coupled to the motor, a retractable plunger, and a mixing attachment. The mixing shaft may be rotatable by the motor. The retractable plunger may be extendable between a first position into the mixing shaft and a second position extending from the mixing shaft. The mixing attachment may be removably attached to the mixing shaft and may define a shaft channel for sliding receipt of the mixing shaft. The mixing attachment may also define an aperture connected with the with the shaft channel and configured for selective receipt of the retractable plunger. The mixing shaft can be inserted into the shaft channel and may be moved to selectively lock the mixing attachment to the mixing shaft by receipt of the retractable plunger into the aperture of the mixing attachment.

Abstract: A system and method are provided for recommending at least one coating composition for coating substrates considering the particular geographical location and the environmental conditions associated with that location. The computer based system and the method can also consider the particular performance and optionally the appearance features desired by the end user.
